A large downward load acting on the side panel at the time of stacking can be directly received by the frame structure, and the fear that the wire rod of the mesh structure is deformed as in the conventional case is eliminated. In other words, it is not necessary to increase the wire diameter of the wire of the mesh structure constituting the load support base in consideration of the load at the time of pallet stacking. Moreover, since the side of the mesh structure of the load support base is used as a means for preventing the side panel from closing inward, it is not necessary to add a special member. Therefore, the weight and cost of the pallet can be reduced as a whole.

更に本発明の構成によれば、フレーム構造体の左右一対の前後方向枠材を構成する上側解放の溝形材の上に架設された部分的に存在する板材でパネル支持部を構成するものであるにもかかわらず、パレット段積み時に上段パレットの荷重を集中して受けるサイドパネルの前後方向２箇所は確実にフレーム構造体側の板面で支持させることができ、サイドパネルの変形を防止することができる。Furthermore, according to the structure of this invention, a panel support part is comprised with the board | plate material which exists partially on the channel material of the upper open side which comprises a pair of right-and-left front-back direction frame material of a frame structure.

Can do.

又、請求項２に記載の本発明によれば、上記効果を得るために、パネル支持部を構成するための特別な板材を追加する必要がなく、構造をシンプルにすることができる。 According to the second aspect of the present invention, it is not necessary to add a special plate material for constituting the panel support portion in order to obtain the above effect , and the structure can be simplified.

又、請求項３に記載の構成によれば、フレーム構造体の左右両側部のパネル支持部を構成する前後方向枠材に、当該パネル支持部に必要な横幅より少し幅広の部材を使用するだけで、支持するサイドパネルが内側に閉動するのを阻止する係合部を構成するメッシュ構造体の左右両側辺をフレーム構造体の前記前後方向枠材で支持させて、メッシュ構造体の耐荷重性能を高めることができる。 Moreover, according to the structure of Claim 3 , only the member a little wider than the width required for the said panel support part is used for the front-back direction frame material which comprises the panel support part of the right-and-left both sides of a frame structure. Thus, the left and right sides of the mesh structure constituting the engaging portion that prevents the supporting side panel from closing inward are supported by the longitudinal frame material of the frame structure, and the load resistance of the mesh structure Performance can be increased.

The left and right direction wire rods 19a located at both front and rear ends of the mesh structure 7 are configured to protrude slightly outward from the front and rear ends of the pair of left and right front and rear direction frame members 16a and 16b in the frame structure 6. Yes.

上記の荷支持台１の構成によれば、荷支持台１の左右両側部に構成されたパネル支持部２５は、前後方向枠材１６ａ，１６ｂ（角パイプ）の天板部で形成される、メッシュ構造体７の上面レベル（上側の左右方向線材１９の上端レベル）より一段低い、前後方向の全長にわたって連続する板面２５ａを備えており、このパネル支持部２５の外側辺に前記折り畳み段積み用支持具１５が位置し、内側辺にメッシュ構造体７の左右両側辺（前後方向線材１８ａの位置）が位置している。従って、このパネル支持部２５で支持されるサイドパネル２，３は、外側に開動することを折り畳み段積み用支持具１５によって阻止され、内側への閉動は、その下側辺がメッシュ構造体７の左右両側辺と係合することにより阻止される。   According to the configuration of the load support base 1 described above, the panel support portions 25 formed on the left and right sides of the load support base 1 are formed by the top plate portions of the front and rear direction frame members 16a and 16b (square pipes). A plate surface 25 a that is one step lower than the upper surface level of the mesh structure 7 (the upper end level of the upper left and right direction wire rod 19) and continuous over the entire length in the front-rear direction is provided. The support tool 15 is located, and the left and right sides of the mesh structure 7 (positions of the front-rear direction wire 18a) are located on the inner side. Accordingly, the side panels 2 and 3 supported by the panel support 25 are prevented from opening outward by the folding stacking support 15, and the inner side of the side panel 2 or 3 is mesh structure. It is blocked by engaging the left and right sides of 7.

又、メッシュ構造体７の左右方向線材１９は、フレーム構造体６における各左右方向枠材１７ａ〜１７ｃには重ならない領域、即ち、各左右方向枠材１７ａ〜１７ｃから前後に適当距離だけ離れた領域にのみ配列され、フレーム構造体６における前後両端の左右方向枠材１７ａ，１７ｂの外側には、メッシュ構造体７の前後両端に位置する各１本の左右方向線材１９ａのみが配置されている。従って、平面視において、各左右方向枠材１７ａ〜１７ｃとこれの前後に隣接する左右方向線材１９，１９ａとの間でも、メッシュ構造体７の網目とほぼ同一サイズの網目が形成されている。   Further, the left and right direction wire 19 of the mesh structure 7 is separated from the left and right direction frame members 17a to 17c in the frame structure 6 by an appropriate distance from the left and right direction frame members 17a to 17c. Only one horizontal wire 19a located at each of the front and rear ends of the mesh structure 7 is arranged outside the left and right frame members 17a and 17b at the front and rear ends of the frame structure 6 that are arranged only in the region. . Therefore, in the plan view, a mesh having substantially the same size as the mesh of the mesh structure 7 is also formed between each of the left and right frame members 17a to 17c and the left and right wire members 19 and 19a adjacent to the front and rear thereof.

図４及び図５に示すように、バックパネル４は、縦線材２０と横線材２１とを適当間隔おきに配列すると共に交叉部で両線材どうしを溶接により結合一体化して構成したメッシュ構造のものであって、バックパネル４の下端から所要長さ延出させた各縦線材２０を内側へ直角に折曲して前後方向線材部２０ａとし、この前後方向線材部２０ａの先端部上と中間部上とにそれぞれ左右方向線材２１ａ，２１ｂを重ねて互いに溶接にて固着することにより、折曲底辺部１０が構成されている。尚、この折曲底辺部１０の左右方向の長さ（幅）は、バックパネル４の垂直本体部の左右方向の長さ（横幅）よりも少し狭く、当該折曲底辺部１０を荷支持台１の後側辺部上の所定位置に載置したとき、その各前後方向線材部２０ａが、荷支持台１のメッシュ構造体７における前後方向線材１８の互いに隣り合う２本の線材間の略中央に位置すると共に、左右方向線材２１ａ，２１ｂが、当該メッシュ構造体７における左右両端の前後方向線材１８ａを除く各前後方向線材１８上に受け止められ、そして折曲底辺部１０の先端の左右方向線材２１ａが、平面視において荷支持台１のフレーム構造体６における後側の左右方向枠材１７ｂと重なるように構成されている。   As shown in FIGS. 4 and 5, the back panel 4 has a mesh structure in which the vertical wires 20 and the horizontal wires 21 are arranged at appropriate intervals, and the two wires are joined and integrated at the crossing portions by welding. And each vertical wire 20 extended to the required length from the lower end of the back panel 4 is bent inward at a right angle to form a front-rear wire member 20a, and on the front end portion and the middle portion of the front-rear wire member 20a The bent bottom portion 10 is configured by superimposing the left and right wire rods 21a and 21b on each other and fixing them together by welding. The length (width) of the bent bottom portion 10 in the left-right direction is slightly narrower than the length (horizontal width) of the vertical main body portion of the back panel 4 in the left-right direction. When placed at a predetermined position on one rear side portion, each of the front and rear direction wire portions 20a is approximately between two adjacent wires of the front and rear direction wire 18 in the mesh structure 7 of the load support base 1. The left and right direction wire rods 21a and 21b are received on the respective front and rear direction wire rods 18 except the front and rear direction wire rods 18a at the left and right ends of the mesh structure 7 and are located at the center, and the left and right direction at the tip of the bent bottom portion 10 The wire 21a is configured to overlap the left and right frame member 17b on the rear side of the frame structure 6 of the load support base 1 in plan view.

上記構成のバックパネル４の折曲底辺部１０と荷支持台１とを連結するヒンジ１１は、３つのヒンジ部材２２ａ〜２２ｃから構成されている。各ヒンジ部材２２ａ〜２２ｃは同一構造のもので、バックパネル４の折曲底辺部１０の左右方向の略中央位置と、両端寄りの左右対称２箇所の３箇所において、バックパネル４の折曲底辺部１０における先端の左右方向線材２１ａに嵌合した状態で、荷支持台１のフレーム構造体６における後側の左右方向枠材１７ｂに溶接により固着され、バックパネル４が折曲底辺部１０における先端の左右方向線材２１ａを中心に起伏自在に取り付けられている。   The hinge 11 that connects the bent bottom portion 10 of the back panel 4 having the above-described configuration and the load support base 1 includes three hinge members 22a to 22c. Each of the hinge members 22a to 22c has the same structure, and the bent bottom side of the back panel 4 is arranged at three positions, a substantially central position in the left-right direction of the bent bottom side portion 10 of the back panel 4 and two symmetrical left and right sides. In a state of being fitted to the left and right direction wire rod 21 a at the tip of the portion 10, the back panel 4 is secured to the rear left and right direction frame material 17 b of the frame structure 6 of the load support base 1 by welding. It is attached so that it can be raised and lowered centering on the left-right direction wire 21a at the tip.

サイドパネル２，３は、バックパネル４と同様に、縦線材２３と横線材２４とを適当間隔おきに配列すると共に交叉部で両線材どうしを溶接により結合一体化して構成したメッシュ構造のものであって、これらサイドパネル２，３とバックパネル４とを連結するコイルヒンジ９は、図４に示すように、バックパネル４の左右両側辺に位置する縦線材２０とサイドパネル２，３の後側辺に位置する縦線材２３とを連結する。そして左右両サイドパネル２，３の下側辺は、各縦線材２３の端面と最下端の横線材２４ａの周面とで形成されており、このサイドパネル２，３の下側辺が、荷支持台１の左右両側部に形成された前記パネル支持部２５で支持されることになる。尚、サイドパネル２，３の各縦線材２３の内、段積み時に上側パレットの各脚体８を支持する領域、即ち、平面視において脚体８と重なる領域にある縦線材２３には、横線材２４を挟むように内側縦線材２３ａを並列追加して、下向き荷重に対する座屈強度を高めている。   As with the back panel 4, the side panels 2 and 3 have a mesh structure in which the vertical wires 23 and the horizontal wires 24 are arranged at appropriate intervals, and the two wires are joined and integrated at the intersections by welding. As shown in FIG. 4, the coil hinge 9 that connects the side panels 2 and 3 and the back panel 4 has a vertical wire 20 positioned on the left and right sides of the back panel 4 and the back of the side panels 2 and 3. The vertical wire 23 located on the side is connected. The lower sides of the left and right side panels 2 and 3 are formed by the end surfaces of the vertical wires 23 and the peripheral surface of the lowermost horizontal wire 24a. It is supported by the panel support portions 25 formed on the left and right sides of the support base 1. Of the vertical wires 23 of the side panels 2 and 3, the vertical wires 23 in the region supporting the legs 8 of the upper pallet when stacked, that is, in the region overlapping the legs 8 in plan view, The inner vertical wire 23a is added in parallel so as to sandwich the wire 24, and the buckling strength against the downward load is increased.

ゲートパネル５と荷支持台１とを連結するコイルヒンジ１３は、ゲートパネル５（下側ゲートパネル部５ａ）の下端の左右方向線材と、図４に示す荷支持台１のメッシュ構造体７における前端の左右方向線材１９ａとを連結する。   The coil hinge 13 that connects the gate panel 5 and the load support base 1 is provided in the left and right direction wires at the lower end of the gate panel 5 (lower gate panel portion 5a) and the mesh structure 7 of the load support base 1 shown in FIG. The front end horizontal wire 19a is connected.

上記構成の荷役用パレットを折り畳むときは、係止手段１４を解除してゲートパネル５をサイドパネル２，３から切り離した状態で、両サイドパネル２，３をコイルヒンジ９での遊びを利用して垂直に少し持ち上げるか又は、バックパネル４を後方に傾けるように両サイドパネル２，３の手前を少し持ち上げて、サイドパネル２，３の下側辺をメッシュ構造体７の左右両側辺を内側へ乗り越えられるように少し高くした状態で、これら両サイドパネル２，３をバックパネル４の内側に重ねるように折り畳む。この後、ゲートパネル５を荷支持台１の上に重ねるように折り畳み、この上に両サイドパネル２，３とバックパネル４との重なりを被せるように折り畳む。このときバックパネル４は、折曲底辺部１０の先端の左右方向線材２１ａを支点に回倒前方下方に倒伏することになり、当該折曲底辺部１０の存在により、荷支持台１との間にゲートパネル５と両サイドパネル２，３とを無理なく挟み込むことができる。   When folding the cargo handling pallet having the above configuration, the locking means 14 is released and the gate panel 5 is separated from the side panels 2 and 3, and the side panels 2 and 3 are used by the play on the coil hinge 9. Lift the front side of the side panels 2 and 3 slightly so that the back panel 4 is tilted backward, and the lower sides of the side panels 2 and 3 are inside the left and right sides of the mesh structure 7. The two side panels 2 and 3 are folded so as to overlap the inside of the back panel 4 in a state of being slightly raised so as to be able to get over. Thereafter, the gate panel 5 is folded so as to overlap the load support base 1, and is folded so that the side panels 2, 3 and the back panel 4 overlap each other. At this time, the back panel 4 turns around forward and downward with the left and right direction wire 21a at the tip of the bent bottom portion 10 as a fulcrum. Thus, the gate panel 5 and the side panels 2 and 3 can be sandwiched without difficulty.

折り畳まれたパレットを使用するときには、上記と逆の手順で展開して組み立てれば良いが、起立させたバックパネル４を後方へ少し倒した状態で両サイドパネル２，３を当該バックパネル４に対して左右に広げ、荷支持台１の左右両側辺から起立する折り畳み段積み用支持具１５の内側にサイドパネル２，３を当接させる。係る状態で両サイドパネル２，３と共にバックパネル４を前方に起こして起立させれば、両サイドパネル２，３の下側辺が、荷支持台１のメッシュ構造体７の左右両側辺から外側に張り出しているパネル支持部２５に自動的に載置されることになる。即ち、荷支持台１のメッシュ構造体７の左右両側辺と折り畳み段積み用支持具１５との間に両サイドパネル２，３の下側辺が嵌合して、当該両サイドパネル２，３の下側辺が、前後方向枠材１６ａ，１６ｂ（角パイプ）の天板部から成る前後方向に連続した平坦な板面２５ａで支持されることになる。この後、ゲートパネル５を起こし、係止手段１４で左右両サイドパネル２，３の前側辺とゲートパネル５の左右両側辺とを連結すれば組立てが完了する。   When a folded pallet is used, it may be unfolded and assembled in the reverse order of the above, but the side panels 2 and 3 are moved relative to the back panel 4 with the back panel 4 erected slightly backward. The side panels 2 and 3 are brought into contact with the inner side of the folding stacking support 15 that stands up from the left and right sides of the load support base 1. If the back panel 4 is raised together with the side panels 2 and 3 in this state, the lower sides of the side panels 2 and 3 are outside from the left and right sides of the mesh structure 7 of the load support 1. It is automatically placed on the panel support portion 25 that protrudes from the panel. That is, the lower side sides of the side panels 2 and 3 are fitted between the left and right sides of the mesh structure 7 of the load support base 1 and the folding stacking support 15, and the side panels 2 and 3 The lower side is supported by a flat plate surface 25a continuous in the front-rear direction composed of the top plate portions of the front-rear direction frame members 16a, 16b (square pipes). Thereafter, when the gate panel 5 is raised and the front side of the left and right side panels 2 and 3 and the left and right sides of the gate panel 5 are connected by the locking means 14, the assembly is completed.

尚、サイドパネル２，３が外側に開くのを阻止する突出部材として、折り畳み段積み用支持具１５を利用しているが、折り畳んだパレットの段積みを行う必要がないために折り畳み段積み用支持具１５が取り付けられない場合には、メッシュ構造体７の上面と略同一高さか又はこれより少し高い程度の突出部材を、荷支持台１のパネル支持部２５の外側に上向きに突設すれば良い。この上向き突出部材としては、図６及び図７に示すように、棒状部材２６をフレーム構造体６の左右両端の前後方向枠材１６ａ，１６ｂの天板部の外側辺近傍位置や図示の外側上出隅部に溶接などで固着することができる。この場合、図示のように長さの短い複数の棒状部材２６を前後方向枠材１６ａ，１６ｂの長さ方向の複数箇所に分けて付設しても良いし、前後方向枠材１６ａ，１６ｂの全長にわたって連続する長尺の棒状部材２６を取り付けても良い。   Although the folding stacking support 15 is used as a projecting member that prevents the side panels 2 and 3 from opening outward, it is not necessary to stack folded pallets, so that folding stacking is not necessary. When the support tool 15 is not attached, a protruding member having a height substantially equal to or slightly higher than the upper surface of the mesh structure 7 is provided to protrude outwardly from the panel support portion 25 of the load support base 1. It ’s fine. As the upward projecting member, as shown in FIGS. 6 and 7, the rod-shaped member 26 is positioned in the vicinity of the outer side of the top plate portion of the front and rear direction frame members 16 a and 16 b at the left and right ends of the frame structure 6 or on the outer side in the drawing. It can be fixed to the protruding corner by welding or the like. In this case, as shown in the drawing, a plurality of rod-like members 26 having a short length may be separately provided at a plurality of positions in the longitudinal direction of the front and rear direction frame members 16a and 16b, or the entire length of the front and rear direction frame members 16a and 16b. A long rod-like member 26 that extends continuously may be attached.

図８〜図１３に示す実施形態では、線材を曲げ加工して構成した倒立Ｕ字形部材２７を上向き突出部材として利用している。この倒立Ｕ字形部材２７は、図８〜図１１に示すように、前後方向枠材１６ａ，１６ｂの外側面を内側に凹入させ、この凹入部２８内に倒立Ｕ字形部材２７の両脚部２７ａを嵌合して溶接により固着することにより、荷支持台１の左右両外側面（前後方向枠材１６ａ，１６ｂの外側面）から倒立Ｕ字形部材２７が突出しないか又は突出量を少なくすることができるが、勿論、図１２及び図１３に示すように、倒立Ｕ字形部材２７の全体が前後方向枠材１６ａ，１６ｂの外側面から突出するように取り付けても良い。何れにしても、この倒立Ｕ字形部材２７を利用するときは、図９に示すように、サイドパネル２，３が外側に開動したときに、当該サイドパネル２，３の横線材２４の外側において前後に隣り合う２本の縦線材２３間に倒立Ｕ字形部材２７が嵌まり込んで、サイドパネル２，３を前後方向において位置決めするように、倒立Ｕ字形部材２７の前後方向の幅と取付け位置とを決めておくのが望ましい。勿論、折り畳み段積み用支持具１５以外の上向き突出部材として、上記の棒状部材２６と倒立Ｕ字形部材２７に限定されるものではなく、前後方向枠材１６ａ，１６ｂの外側面に当て付けて溶接できる帯状板材など、他の任意のものを利用することができる。   In the embodiment shown in FIGS. 8 to 13, an inverted U-shaped member 27 formed by bending a wire is used as the upward projecting member. As shown in FIGS. 8 to 11, the inverted U-shaped member 27 has the outer side surfaces of the front and rear direction frame members 16 a and 16 b recessed inside, and the both leg portions 27 a of the inverted U-shaped member 27 in the recessed portion 28. And the U-shaped member 27 does not protrude from the left and right outer surfaces of the load support base 1 (the outer surfaces of the front and rear frame members 16a and 16b) or the amount of protrusion is reduced. Of course, as shown in FIGS. 12 and 13, the entire inverted U-shaped member 27 may be attached so as to protrude from the outer surfaces of the front and rear frame members 16 a and 16 b. In any case, when the inverted U-shaped member 27 is used, as shown in FIG. 9, when the side panels 2 and 3 are moved outward, on the outside of the horizontal wire 24 of the side panels 2 and 3. The width and mounting position of the inverted U-shaped member 27 in the front-rear direction so that the inverted U-shaped member 27 is fitted between the two vertical wires 23 adjacent to each other in the front-rear direction and the side panels 2 and 3 are positioned in the front-rear direction. It is desirable to decide. Of course, the upward projecting member other than the folding stacking support 15 is not limited to the rod-shaped member 26 and the inverted U-shaped member 27, but is applied to the outer surfaces of the front and rear frame members 16a and 16b for welding. Other arbitrary materials such as a strip-shaped plate material that can be used can be used.

又、先の実施形態では、メッシュ構造体７の左右両側辺をフレーム構造体６の左右両端の前後方向枠材１６ａ，１６ｂ上に載置固着したが、図８に示すように、メッシュ構造体７の左右両側辺をフレーム構造体６の左右両端の前後方向枠材１６ａ，１６ｂ上に載置しない状態で、フレーム構造体６上にメッシュ構造体７を取り付けても良い。   In the previous embodiment, the left and right sides of the mesh structure 7 are placed and fixed on the front and rear frame members 16a and 16b at the left and right ends of the frame structure 6. However, as shown in FIG. The mesh structure 7 may be mounted on the frame structure 6 in a state where the left and right sides of the frame 7 are not placed on the front and rear frame members 16 a and 16 b at the left and right ends of the frame structure 6.

フレーム構造体６は、少なくとも左右２本の前後方向枠材１６ａ，１６ｂとこれら両前後方向枠材１６ａ，１６ｂを連結する少なくとも前後２本の左右方向枠材１７ａ，１７ｂから形成される矩形周囲枠を備えていることが必須構成要件となるが、この矩形周囲枠は、図９〜図１０に示すように、前後２本の左右方向枠材１７ａ，１７ｂの左右両端部をその対向内側面において前後方向枠材１６ａ，１６ｂで連結することにより構成することもできる。この構成によれば、荷支持台１のメッシュ構造体７から左右両外側に張り出すフレーム構造体６の左右両側部が、前後方向枠材１６ａ，１６ｂとその前後両端部に位置する左右方向枠材１７ａ，１７ｂの端部とで構成されることになる。従って、メッシュ構造体７から左右両外側に張り出すフレーム構造体６の左右両側部の前後方向全域をパネル支持部２５とする場合には、図１０に示すように、前後方向枠材１６ａ，１６ｂとその前後両端部に位置する左右方向枠材１７ａ，１７ｂの端部の上面（各枠材の天板部の上面）を面一にすれば良い。この構成では、脚体８は左右方向枠材１７ａ，１７ｂの両端部下側に固着されることになる。 The frame structure 6 is a rectangular peripheral frame formed of at least two left and right front and rear frame members 16a and 16b and at least two front and rear left and right frame members 17a and 17b that connect both the front and rear frame members 16a and 16b. However, this rectangular peripheral frame is provided with the left and right end portions of the two front and rear left and right frame members 17a and 17b on the opposite inner side surfaces as shown in FIGS . It can also comprise by connecting with the front-back direction frame materials 16a and 16b. According to this configuration, the left and right sides of the frame structure 6 projecting from the mesh structure 7 of the load support base 1 to the left and right outer sides are positioned at the front and rear frame members 16a and 16b and the front and rear ends. It is comprised by the edge part of material 17a, 17b. Therefore, when the entire front-rear direction of the left and right side portions of the frame structure 6 projecting outward from the mesh structure 7 to the left and right sides is used as the panel support portion 25, the front-rear direction frame members 16a, 16b as shown in FIG. And the upper surface (the upper surface of the top plate portion of each frame member) of the end portions of the left and right direction frame members 17a and 17b located at both front and rear ends thereof may be flush with each other. In this configuration, the leg body 8 is fixed to the lower side of both end portions of the left and right direction frame members 17a and 17b.

上記構成のフレーム構造体６の場合、左右方向枠材１７ａ，１７ｂは、バックパネル４やゲートパネル５と荷支持台１のメッシュ構造体７とを連結するヒンジの関係で、先の実施形態で示した左右方向枠材１７ａ，１７ｂと同様に、荷支持台１の前後両側辺より内側に少し入った位置に配置されるので、左右両サイドパネル２，３の前端部が、図９の左側で示すように、フレーム構造体６から前方に突出することになり、パネル支持部２５の全長がサイドパネル２，３の下側辺の全長に比較して短くなる。これが問題になるようなときは、図９の右側に仮想線で示すように、左右方向枠材１７ａ，１７ｂの端部の前後両外側に、この左右方向枠材１７ａ，１７ｂの端部を介して前後方向枠材１６ａ，１６ｂを前後方向に延長する延長枠材２９を付設することができる。   In the case of the frame structure 6 configured as described above, the left and right frame members 17a and 17b are hinged to connect the back panel 4 and the gate panel 5 and the mesh structure 7 of the load support base 1 in the previous embodiment. Like the left and right direction frame members 17a and 17b shown in the figure, the left and right side panels 2 and 3 are arranged on the left side of FIG. As shown in FIG. 6, the panel structure 25 protrudes forward from the frame structure 6, and the total length of the panel support portion 25 is shorter than the total length of the lower side of the side panels 2 and 3. When this becomes a problem, as shown by phantom lines on the right side of FIG. 9, the ends of the left and right direction frame members 17a and 17b are provided on both the front and rear sides of the end portions of the left and right direction frame members 17a and 17b. Thus, an extension frame member 29 that extends the front-rear frame members 16a and 16b in the front-rear direction can be attached.

メッシュ構造体７は、前後方向線材１８の上に左右方向線材１９を載置固着して構成したが、逆であっても良い。この場合、図３に示すように、フレーム構造体６の前後方向枠材１６ａ，１６ｂの内側に左右方向枠材１７ａ〜１７ｃが結合されているときは、前後方向枠材１６ａ，１６ｂの上面を左右方向線材１９の線径分だけ左右方向枠材１７ａ，１７ｂの上面より低くすれば、前後方向線材１８は各左右方向枠材１７ａ〜１７ｃの上面で支持させると共に、左右方向線材１９の両端部は前後方向枠材１６ａ，１６ｂの上面で支持させ、前後方向枠材１６ａ，１６ｂの天板部の上面をパネル支持部２５の板面２５ａとすることができる。
次に、本発明の構成を適用した実施例について説明すると、図９及び図１１に示すように、フレーム構造体６の左右方向枠材１７ａ，１７ｂの内側に前後方向枠材１６ａ，１６ｂを結合し、この前後方向枠材１６ａ，１６ｂの上面を左右方向線材１９の線径分だけ左右方向枠材１７ａ，１７ｂの上面より低くすることにより、前後方向線材１８は各左右方向枠材１７ａ、１７ｂの上面で支持させると共に、左右方向線材１９の両端部は前後方向枠材１６ａ，１６ｂの上面で支持させることはできるが、サイドパネル２，３は、一段高い左右方向枠材１７ａ，１７ｂの両端部でのみ支持されることになる。換言すれば、この本発明の構成では、荷支持台１のメッシュ構造体７の左右両外側に張り出すフレーム構造体６の左右両側部に設けるパネル支持部２５は、左右方向枠材１７ａ，１７ｂの両端部の天板部の板面２５ａで構成されることになるが、この左右方向枠材１７ａ，１７ｂの両端部の下側に脚体８が固着されているので、パレット段積み時に上段パレットからの荷重が集中するサイドパネル２，３の前後２箇所、即ち、脚体８の真上領域が、パネル支持部２５の板面２５ａで支持されることになり、当該サイドパネル２，３の他の領域がパネル支持部２５で支持されていなくとも問題はない。尚、前後方向線材１８に対して左右方向線材１９が下になる場合でも、図１１に示すように、ゲートパネル５をコイルヒンジで連結することになる最前端の左右方向線材１９ａは、前後方向線材１８の上に配設するのが望ましい。 The mesh structure 7 is configured by mounting and fixing the left-right direction wire 19 on the front-rear direction wire 18, but may be reversed. In this case, as shown in FIG. 3, when the left and right frame members 17a to 17c are coupled to the inside of the front and rear frame members 16a and 16b of the frame structure 6, the upper surfaces of the front and rear frame members 16a and 16b are If the wire diameter of the left and right direction wire 19 is lower than the upper surface of the left and right direction frame members 17a and 17b, the front and rear direction wire 18 is supported on the upper surface of each of the left and right direction frame members 17a to 17c. Can be supported by the upper surfaces of the front and rear direction frame members 16a and 16b, and the upper surface of the top plate portion of the front and rear direction frame members 16a and 16b can be used as the plate surface 25a of the panel support unit 25 .
Next, an embodiment to which the configuration of the present invention is applied will be described . As shown in FIGS. 9 and 11, the front and rear frame members 16 a and 16 b are coupled to the inner side of the left and right frame members 17 a and 17 b of the frame structure 6. and, the front-rear direction frame member 16a, the upper surface only line diameter in the horizontal direction wire 19 directional frame member 17a of 16b, by lower than the upper surface of the 17b, the front-rear direction wire 18 each directional frame member 17a, 17b The both ends of the left and right direction wire rod 19 can be supported by the upper surfaces of the front and rear direction frame members 16a and 16b. However, the side panels 2 and 3 are arranged at both ends of the left and right direction frame members 17a and 17b. It will be supported only by the department.
